4 Claims.

This invention relates to a window frame putty groove cleaning device.

In the reglazing of windows, or openings in doors and the like, it isfrequently a rather long and laborious task to remove the old, dried outputty, points, and the like, from the groove into which the glass is tobe fitted. The device of my present invention is so arranged andconstructed that this operation can be carried out in a simple andefficient manner in a much shorter time than was heretofore possiblewhen the job was done by hand. My device includes a motor for driving arotatable cleaning tool that extends into the putty groove and removestherefrom the old putty, points, and the like. Adjustable guide rollersare provided for bearing against surfaces at right angles to each otherand on opposite sides of the groove, with means for holding the rollersin adjusted position in accordance with the depth of the groove so thatthe cleaning tool may clean the groove to the full depth thereofwithout, however, cutting into the wood. Thus, by the operation of mydevice, window frame putty grooves can be cleaned quickly andefficiently without danger of cutting into the sides of the groove orenlarging the same.

It is therefore an object of this invention to provide a window frameputty groove cleaning device of the general type indicated which iscapable of efficiently and quickly removing the old putty without injuryto the groove itself.

Other and further important objects of this invention will be apparentfrom the disclosures in the specification and the accompanying drawing.

This invention (in a preferred form) is illustrated in the drawing andhereinafter more fully described.

As shown on the drawing:

The reference numeral 50 indicates generally a window frame putty groovecleaning device em- 5 bodying the principles of my invention. Saiddevice I!) comprises an electrical motor 1 I having a lead-in wire !2and plug 13 for connecting said motor to a source of electrical energy.The shaft 14 of said motor H carries a .chuck 5, 10 into which acleaning tool l6 may be removably inserted and held. As shown in Fig. l,the tool 16 is provided with a fluted or serrated cylindr cal surfacefor rotation against one surface wall I! of a groove !8 formed in thelower portion ofthe window frame 19. The end surface of the cleaningtool it (Fig. 2) is provided with serrations or teeth 20 for cleaningout putty or the like from the other wall surface 2| of said groove 18.20

In Fig. 3 there is shown a modified form of cleaning tool identified bythe reference numeral 22 for cleaning a groove 23 in the upper rail 24of a window frame.

It will be understood, of course, that the clean- 25 ing tool proper ofmy device may be of such shape and dimensions as to adapt it for thecleaning of any form or shape of groove used in the glazing of windows,doors, or the like. The cleaning surfaces of the tool, however, in allinstances are so formed and designed as not to be capable of cuttinginto or injuring the wood forming the sides or walls of the groove to becleaned. This is accomplished by giving a lead to the curved serrations6!) of the tool surface such that the inner ends of said serrations 60,scrape first against the groove wall 11 near the bottom thereof, asshown in Fig. 1. The curved serrations or cutting edges 60 of the toolsurface tend to lift up the glazing points by engagement of a serrationwith a point, as the tool moves through a groove, to thus displace suchglazing point. Rotation of the tool thus tends to lift out of the grooveany points that may have been left therein, instead of driving them in,and to clean the putty out of the groove instead of cutting into thewood.

The device Hl includes a support, indicated generally by the referencenumeral 25, which is secured to the motor casing H and which comprises apair of offset arms 26 and 21 spaced on opposite sides of the motorshaft !4 and joined by a plate 28, which extends transversely of saidmotor shaft 14 and is apertured, as at 29, to permit the shaft of thetool 16 or 23 to.

extend therethrough and to permit also'of the removal therethrough ofthe chuck i5 shouid that become necessary. A handle is secured to saidplate 28 and extends therefrom to facilitate movement of the device byhand along the groove that is to be cleaned.

A post 3| extends from the underside of the plate 28 in substantialalignment with the arm 21. Said post 3| is transversely bored near theend thereof, as at 32, to receive a stem 33 carrying at its innerbifurcated end 34, a roller 35. Said stem 33 is movable in the bore 32and may be held in adjusted position by means of a thumb bolt 36, thethreaded portion 31 of which may be screwed into said post 3| against aface of the stem 33. The bore 32 is counterbored, as at 39, and a coiledspring 40 positioned with one end bearing against the bottom of saidcounterbore and the other end bearing against the bifurcated end 34 ofthe stem. With this arrangement, the spring 40 tends to urge the rollerand its sup porting stem 33 into an inwardly projected posi tionwhenever released by the thumb screw 36, i. e., downwardly, as viewed inFigure 2. This arrangement thus facilitates the adjustment of the roller35 into rolling contact with a surface, such as the surface 4| (Fig. 1),in accordance with the depth of the groove l8.

A second roller 42 is carried by the plate 28 with its axis at rightangles to the axis of the motor. shaft l4 and with its roller portionextending through an opening 43 in said plate 28. Said roller 42comprises adisk 44 (Figs. 4 and 5) having a flange 45 extending part wayabout its periphery. Said disk 44 is provided with a threaded opening 46for receiving the reduced threaded end 41 of a thumb screw 48. saidthumb screw 48 extends through a lug 49 which maybe formed integrallywith the plate 28. A smoothly tapered shoulder 5|! is provided betweenthe reduced threaded end 46 and the smooth shank 5| of said thumb screw48. A coiled spring 52 is positioned about the shank 5| adjacent saidshoulder 50, with an extended end. 53 thereof bearing against a portionof the flange 45. Since the end 53 of the spring 52 is under torsionalstress when the roller 42 is in the position shown in Fig. 4, there is atendency, when the thumb screw 48 is loosened, for the-spring to movethe roll 42 about its eccentric axis provided by the threaded end 41 toproject the roller portion through the opening 43 against a surface,such as the surface 54 (Fig. 1). A ring 55 loosely mounted upon theflange 45 of said disk 44 is thus brought into rolling engagement withsaid surface 54 and the thumb screw 48 is tightened up to hold the disk44 in its adjusted position. Sufficient clearance, as at 56, is providedbetween the disk 44 and the plate 28 to keep the ring 55 from bindingduring its rotation about the disk 44.

When it is desired to clean out a groove such as the groove I8 (Fig. 1),a small portion of the groove is first cleaned out by hand so that thetool Hi can be properly fitted into that portion of the groove and therollers 35 and 42 moved into their adjusted position and secured inplace by the respective thumb screws 36 and 48. The motor II is thenenergized and the tool it gradually moved through the full length of thegroove l8 from end to end. During such movement, the roller 35 rollsover the surface 4| and the roller 42 rolls over the surface 54 to limitthe extent to which the tool I6 can extend in the direction of either ofthe surfaces i1 and 2|, re-

spectively. By so limiting the depth to which the tool I6 may move inthe direction either of the walls of the groove, cutting of or injury tothe walls themselves is thereby prevented.

The cleaning of a groove, such as the groove 23 (Fig. 3) with a modifiedform of tool 22 is carried out in a similar way, the rollers 42 and 35bearing against surfaces at right angles to each other and on oppositesides of the groove. In this case the width of the cleaning face of thetool 22 is the same as the width of the groove, so that the tool may berotated in the groove up to the desired depth as determined by thesetting of the rollers 35 and 42.

I am aware that many changes may be made and numerous details ofconstruction may be from the principles of this invention, and I, variedthrough a wide range Without departing therefore, do not purposelimiting the patent granted hereon otherwise than necessitated by theprior art.

The term length of cut is herein used to define the amount of cutperformed by the cutter in horizontal direction as viewed in thedrawing, and the term depth of cut is used to designate the amount ofcut in a vertical direction as viewed in the drawing.
